Arne Klungland group

Laboratory for Genome repair and regulation

Institute of Medical Microbiology, Section for Molecular Biology, is localised at Oslo University Hospital, Rikshospitalet,  Gaustad, Oslo. Four different research groups are colocalised, concentrating on DNA-repair and epigenetic studies, brain development, microbiology and biocomputing. 

We have a very close collaboration with the Bjørås group which is also a part of the Stem Cell Centre, as well as  biocomputing collaborations with the Rognes group. For characterization of knockout mice we collaborate with the Falnes (University of Oslo) and Krokan (University in Trondheim) groups. We also collaborate with excellent research groups in Germany, France, China, Holland, UK and USA. 

Our aim is to elucidate new mechanisms of demethylation and hydroxylation required for for repair and regulation of the mammalian (epi)genome and to address (epi)genome instabilities associated with diseases such as cancer. Our current models also include genes affecting post translational modifications in RNA and proteins. 

Currently we have MSc ("hovedfag"), PhD students and post docs from The Agricultural University, University of Oslo, University of Trondheim ("Siv. Ing."), Austria, Sweden, The Phillipines, Germany and USA.
